CE 3372 – Water Systems Design FALL 2015 CE 3372 – Water Systems Design Exercise Set 6 Purpose: Develop expertise in application of Manning’s equation, and flow geometry in Open Channel Flow ABET General Criteria 3: (a) . . . apply knowledge of mathematics, science, and engineering (e) . . . solve engineering problems (k) . . . an ability to use the techniques, skills, and modern engi- neering tools necessary for engineering practice. Exercises 1. Water flows at 8 m 3 /s through a rectangular channel 4 m wide and 3 m deep. If the velocity is 1 m 3 /s , calculate the flow depth in the channel. If this channel expands (downstream) to a width of 5 m and the depth decreases by 0.5 m from the upstream depth, what is the mean section velocity in the expanded section? i Sketch the cross sections (there are two) and label the width, depth, and channel wall height. ii Write the appropriate relationship between velocity, depth, and discharge for each section.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
